More Book Details

Description of the Book:

A series of idealized models are considered which incorporate the characteristics of an embedment media, a structure and internal equipment. The equipment has natural frequencies which are high compared with the fundamental frequency of the structure. The purpose of the analysis is to obtain exact solutions to the idealized model. These may eventually be compared with solutions obtained by standard structural dynamics techniques to improve understanding of the degree of refinement needed in modeling and to provide guidance for selecting appropriate numerical integration techniques. Certain results on the vibration of equipment have been obtained which appear to be new. These techniques are applied to a structure-equipment system using models that are representative of silo-like protective structures. Excitations simulating ground shock, air shock and shaker loading are examined. (Author
